Experiment Study on Detection of Sulfolane in Water by Gas Chromatography

目的建立一种测定水中环丁砜的方法。方法采用气相色谱—氢火焰检测法。结果相关系数为;0.9982,线性范围0.015～0.200μg,检出限为:1.5mg/L。样品加标回收率为:96.7%～105.4%。结论本方法具有干扰小、线性范围宽、操作简便快捷、结果可靠的优点,适合于测定水中环丁砜的含量。

Objective To establish a method for detection of sulfolane in water Methods Gas Chromatography was adopted. Results The correlation coefficient was 0.9982 and the linear range was from 0.015 μg to 0.200 μg. The detection limit was 1.5 mg/L. The recovery rate range of sample was 97.6 % - 105.4%. Conclusions The method is low disturb, simple, rapid, reliable and has broad linear range. It is suitable for detecting the content of sulfolane in water.
